2. Never allow child ren t o oper ate ri der mo wer . Do not allow adults to operate without pr oper instruction.
3. Clear the area to be mowed of any foreign objects which may be picked up and thrown by cutter blades. Pick up all sticks, stones, wire, and any other debris.
4. Keep everyone, especi all y child re n an d pets, a safe distance away from the area being mowed.
Do not mow with bystanders in the area.
5. Do not operate the machine barefoot or wearing sandals, sneakers, tennis shoes, or similar light­weight footwear. Wear substantial protective
footwear.
10
Safety Instructions
6. Do not wear loose fitting clothing that could get caught in moving parts. Do not operate this machine while wearing shorts; always wear adequate protective clothing, including long pants. Wearing safety glasses, safety shoes, and a helmet is advisable and required by some local ordinances and insurance regulations.
7. Prolonged exposure to loud noise can cause impairment or loss of he ar ing . Operator hear- ing protection is recommended; particularly for continuous operation of the GHS Model due to blower noise level. Wear a suitabl e hearing protective device, such as earmuffs or earplugs.
8. Keep all protective shields and safety de- vices in place. If a protective shield, safety device, or decal is damaged, unusable, or miss­ing, repair or replace it before operating the machine.
9. Be sure interlock switches are functioning correctly, so th e engine cannot be starte d un­less the Forward Speed Control lever is in the NEUTRAL-PARK position, and the PTO clutch is in the DISENGAGED position. Also, the engine should stop if the operator lifts off the seat with the PTO clutch in the ENGAGED position.
10. Handle gasoline with car e. Gasoline is highly flammable and its vapors are explosive :
a. Use an approved fuel container. b. Never add fuel to a run ning engine or ho t
engine (allow hot engine to cool several minutes).
c. Keep matches, cigarettes, cigars, pipes,
open flames, or sparks away from the fuel tank and fuel container.
d. Always fill the fuel tank outdoors using care.
Fill to about one inch from the top of the tank. Use a funnel or spout to prevent spilling.
e. Replace the machine fuel cap and container
cap securely a nd clean up any s pilled fuel before starting the engine.
11. Never attempt to make any adjustments while the engine is running, except where spe­cifically instructed to do so.
12. The elec trical system battery contains sulfuric acid. Avoid any contact with skin, eyes, and clothing. Keep the battery and acid out of reach of children.

OPERATING

1. Operate th e mower only i n daylight or in good artificial light with good visibility of the area being mowed.
2. Sit on the seat when starting the engine and operating the machine. Keep feet on the deck footrests at all times when the tractor is moving and/or mower blades are operating.
3. For a beginning operator, learn to steer
(maneuver) the tractor with a slow engine speed before attempting any mowing oper­ation. Be aware that, with the front mounted
mower configuration, the back of the tractor swings to the outside during turns.
4. Remember, for an emergency stop, the forward motion of th e tractor can always be stopped by pulling the Forwar d Speed Control (F SC) into the NEUTRAL-PARK position.
5. In case either of the transmission drive belts break during operation, and if the machine is on a slope, the machine will f reewheel down the slope. To maintain control, immediately (1) Release the steering levers and simultaneously (2) Move the FSC to the NEUTRAL-PARK posi­tion. When the machine is sto pped or moving slowly, engage the parking brake.
NOTE: This is exac tly th e same proced ure us ed to normally stop and park the machine.
6. Disengage the blade clutch and put the FSC in the NEUTRAL-PARK position before starting the engine (an ignition interlock switch normally prevents starting of the machine if these controls are in the OPERATING position).
7. Do not run the engine in a confined area without adequate ventilation. Exhaust fumes are hazardous and can be deadly.
8. Do not carry passengers - maximum seati ng capacity is one (1) person.
11
Safety Instructions
9. Watch for holes, rocks, and roots in the terrain and for other hidde n hazards. W hen mowing tall grass, mow hig her than desired to e xpose any hidden obstacles. Then, clean the area and mow to the desired height.
10. Avoid sudden start s or stops. Bef ore backing the machine up, look to th e rear to b e sure n o one is behind the machine. Watch carefully for traffic when crossing or working near roadways.
11. Disengage the blade drive when transporting the machine across drives, sidewalks, etc. Never
raise the mower deck while blades are rotating.
12. The maximum recommended side slope operating angle is 20 degrees or 33% grade.
When operating the machine on a slope, reduce speed and use caution to start, stop, and maneuver. To prevent tipping or loss of control of the machine, avoid sharp turns or sudden changes in direction.
13. Never adjust cutti ng height with the engine running. Before adjusting cutting height or servicing, disengage the blade clutch (PTO), stop the engine, and remov e the ignition key. Wait for all movement to stop before getting off the seat.
NOTE: A blade/blower br ake should nor mally stop drive line rotation within five (5) seconds of disengaging the PTO clutch.
17. For GHS equipped models, use care when closing the grass catcher door . Keep fingers and hands away from the hinge and pinch points when the door is be ing closed. Also, k eep fin­gers and hands clear of the do or frame. The door is held closed with s prings and the door may slam shut with considerable force.
18. In case of a clogged or plugged mower deck
or GHS catching system:
a. Disengage the blade clutch (PTO) and turn
the engine off before leaving the seat.
b. LOOK to make sure blade drive sh aft and
blower drive pulley movement has stopped
before trying to unclog the system. c. Disconnect the spark plug wire. d. Never place hands under the deck or in the
GHS blower - use a stick or similar tool to re-
move clogged material.
19. If the cutting bl ades strike a solid object o r the machine begins to vibrate abnormally, immedi-
ately disengage the blade clutch (PTO), stop the engine, and wait for all moving parts to stop. To pr event accidental starting, discon-
nect the spark plug wire. Thoroughly inspect the mower and repair any damage before restarting the engine and operating the mower. Make sure cutter blades are in good condition and blade nuts are torqued to 60 ft-lb (81.3 N
m).
12
14. For side discharge mower decks, do not oper-
ate with the grass deflector chut e removed .
Keep the deflector in the lowest possible position.
15. For tractors equipped with tilt-up deck, observe
the following recommendations:
a. Do not move tractor with deck in tilt-up po-
sition.
b. Never tilt body forward with deck in tilt-up
position.
16. For GHS equipped models, do not operate the
machine with the grass catcher in the DUMP position or with the back door OPEN. Dan-
gerous projectiles may be thrown out of the discharge chute or the back of the grass catcher.
20. Do not touch the engine or muffler while the engine is running or immediately after stop­ping the engine. These areas may be hot enough to cause serious burns.
21. When leaving the machine unattended, dis-
engage the blade clutch (PTO), stop the engine, and remove the key.

MAINTENANCE

1. To prevent accidental starting of the engine when servicing or adjusting the machine, re­move the key fro m the ignition sw itch and dis­connect the spark plug wire.
2. To reduce fire hazards, keep the engine free of grass, leaves, excessive grease, and dirt.
Safety Instructions

Dry Battery Servic e

DANGER
Activating a battery can be dangerous. The battery should be taken to a reliable service station, battery store, or power equipment dealer where a trained techni­cian can activate the b attery safely. DO NOT attempt to activate the battery unless you are experienced in battery service work. The following activation and charg­ing instructions are provided for use by a trained battery technician.
DANGER
Battery electrolyte is a poisonous and cor­rosive sulfuric acid solution.
Avoid spillage and contact with skin,
eyes, and clothing - causes severe burns.

Battery Service

Tilt mower body up (lift on rear of body ) for battery access. Check the bat tery for electr olyte level an d charge. The electrolyte level should be at the bottom of the vent wells [1/4 to 1/2 in. (6 to 13 mm) ab ove plates]. If the specific gravity is less than 1.225, the battery needs charging. If the battery has been shipped dry, or is wet but needs service, refer to the following instructions.
IMPORTANT: Make sure battery is securely mounted in the frame. A loose battery may cause damage to the case resulting in acid leakage and se­vere damage to the machine. A hazard may be cre­ated by damage to cr itical work ing parts and sa fety systems.

Wet Battery Service

If the battery has been shipped wet, but the electro­lyte level is low or the batte ry needs to be charge d then:
1. Fill each battery cell with drinking water to th e bottom of the vent wells.
2. Charge battery. Refer to Battery Charging in this section.
To prevent accidents, wear safety gog-
gles and rubber gloves when working with electrolyte.
Neutralize acid spills with baking soda
and water solution.
T o fill (activate) battery with electrolyte (if battery has been shipped dry):
1. Remove the battery hold dow n bar, disconnect the battery cables and li ft the battery ou t of the tray.
IMPORTANT: Battery must be removed from the mower before filling with electrolyte.
IMPORTANT: Obtain and use only battery grade sulfuric acid electrolyte with a 1.265 spe­cific gravity to activate the battery. DO NOT use water or any other liquid during initial activation.
2. Remove the filler caps and carefully fill each cell until the electrolyte is just above the plates.
3. After the battery is filled with electrolyte, replace the filler caps and cha rge the batt ery. Refer to Battery Charging.

Battery Charging

DANGER
BATTERIES PRODUCE EXPLOSIVE GASES
Charge the battery in a well-ventilated
area, so that gases produced while charg­ing can dissipate.
Keep sparks, flames, and smoking mate-
rials away from the battery at all times.
Battery Clamp
Secured by
Wing Nuts
(+) Battery Cable
Connection
RH Drive Wheel
Make sure the battery cap vents are open
after the battery is filled with acid (check manifold vent on each cap).
Make sure the battery charger is unplug-
ged before connecting or disconnecting cables to the battery.
1. Charge the battery at 15 amps for 10 minutes. DO NOT exceed 20 amps maximum recom­mended charging rate. Charge until specific gravity is at least 1.250. Total charging time should not exceed one (1) hour.
2. After charging the battery, adjust the electrolyte level to the bottom of the vent wells [1/4 to 1/2 in. (6 to 13 mm) above the plates].
IMPORTANT: DO NOT overfill the battery. Electrolyte will overflow through the vented caps onto parts of the machine and WILL result in severe corrosion.
3. Install battery.

Deck Caster Wheels Installation

1. Remove the bolt, nut, axle spacer tube, and spacer washers from each deck caster wheel fork.
NOTE: Spacer washers are used only when the optional semi-pneumatic deck wheels (8.25 x 2.75) are installed.
2. Fit the axle spacer tube through the wheel hub, position the spacer wa sh er on ea ch si de of the hub (if used), and fit the assembly into the wheel fork.
3. Insert the 3/8-16 x 4-1/2 in. bolt through the wheel fork with the bolt head to the outside and install the 3/8-16 in. Keps nut.
4. Tighten the bolt and nut until the axle spacer tube bottoms against the inside of the wheel fork (will not turn) while the wheel and spacer washers (if used) spin freely without binding.
IMPORTANT: Make sure battery is securely mounted in the frame. A loose battery may cause damage to the case resu lting in acid leakage and severe damage to the machine. A hazard may b e created by damage to critical working parts and safety systems.
Install the battery in the mower as shown in Battery Installation photo. Connect the positive and nega­tive cables to the proper battery terminal [red cable
and boot connects to the positive (+) terminal].
Slide the rubber boot up and over the ba ttery post, making sure it co vers the post complet ely to prevent
an electrical short.
